An ethnographic collection of the Waiwai was presented to the museum in 1991 by Guyanese Cultural anthropologist Dr George P. Mentore.

The museum's collections also include excavated artifacts from all of the ten Administrative Regions of Guyana.

Other publications include monographs by renowned scholars in the sub-disciplines of anthropology and children's books on prehistoric Guyana.

A scientific advisory committee monitors and advises the Walter Roth Museum of Anthropology on the research programmes generally, but particularly with respect to the coordination of national programmes with ongoing investigations in anthropology in South America and the Caribbean.

The committee also monitors the museum's journal the objective of maintaining and/or improving its scientific standard.
